A method for establishing a communication channel between a local server and a remote server includes: i) transmitting, from the local server to a terminal, the IP address of the remote server and a communication port of the local server; ii) transmitting the IP address of the terminal from the terminal to the local server; iii) transmitting, from the local server to the terminal, a request to connect to the remote server, including the IP addresses of the remote server and the terminal, an identifier of the local server; and the communication port; iv) transmitting, from the local server to the remote server, the IP address of the terminal, an identifier of the local server, and the communication port; and v) combining, at the remote server, the identifier of the local server and the IP address of the terminal to ascertain an IP address of the local server.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for establishing a two-way IP communication channel in a telecommunications network between a local server, reachable via an IP connection of a terminal, and a remote server, comprising: i) transmitting, from said local server to said terminal, an IP address of said remote server and a communication port number of said local server; ii) after establishing said IP connection between said telecommunications network and said terminal, transmitting an IP address of said terminal from said terminal to said local server; iii) transmitting, from said local server to said terminal, a request to connect to said remote server, said request including: the IP address of said remote server, the IP address of said terminal, an identifier of said local server; and said communication port number of said local server; iv) after establishing a first IP communication channel between said terminal and said remote server, transmitting, from said local server to said remote server: the IP address of said terminal, the identifier of said local server, and said communication port number of said local server; v) combining, at said remote server, said identifier of said local server and the IP address of said terminal in order to ascertain the IP address of said terminal, within the telecommunications network, by which said remote server links to said local server.
2. The method according to claim 1 , wherein step (ii) comprises connecting said terminal to said telecommunications network and transmitting the IP address of said terminal to said local server.
3. The method according to claim 1 , wherein said local server is aboard a universal integrated circuit card (UICC).
4. The method according to claim 3 , wherein said UICC is included within said terminal.
5. The method according to claim 1 , wherein said telecommunications network is an LTE network.
